普陀電熔鎂砂主要有三(san)大(da)種(zhong)類；一(yi)、普通(tong)電(dian)熔(rong)鎂砂，二、低硅高鈣電(dian)熔(rong)鎂砂，三(san)、大(da)結晶電(dian)熔(rong)鎂砂；  

1、普通電熔鎂砂產品主要是選用47%以上含量菱鎂石或輕燒鎂砂為主要原料在電弧中高溫熔融而成。方鎂石晶粒大，結構致密，抗渣性強，高溫體積穩定性優越。電熔鎂砂的主(zhu)要(yao)用(yong)途：電熔(rong)鎂(mei)砂主(zhu)要(yao)是用(yong)于堿性磚、含碳制品和不定(ding)型耐火材料的良好原料。

 2、低硅(gui)高(gao)鈣(gai)(gai)電(dian)熔(rong)鎂(mei)砂(sha)產品主要是選用低硅(gui)菱鎂(mei)石為原(yuan)料，經高(gao)溫電(dian)熔(rong)爐熔(rong)煉而成的。其特點(dian)(dian)是鈣(gai)(gai)硅(gui)比大于 2 ，晶粒(li)發育充(chong)分(fen)，顆(ke)料體積密(mi)度(du)大于 3.50g/cm3以上。低硅(gui)高(gao)鈣(gai)(gai)點(dian)(dian)熔(rong)鎂(mei)砂(sha)主要用于中(zhong)頻感應電(dian)爐熔(rong)煉、高(gao)錳(meng)鋼、不銹(xiu)鋼、高(gao)鑼鋼、堿性磚、含碳制(zhi)品和不定型耐(nai)火材料的良好原(yuan)料。

3、大結(jie)(jie)(jie)晶電(dian)(dian)熔(rong)(rong)鎂(mei)(mei)(mei)砂(sha)生(sheng)產(chan)工(gong)(gong)藝：大結(jie)(jie)(jie)晶電(dian)(dian)熔(rong)(rong)鎂(mei)(mei)(mei)砂(sha)主要是(shi)選用精(jing)選的特級天然(ran)菱鎂(mei)(mei)(mei)石或優(you)質高(gao)純輕燒鎂(mei)(mei)(mei)顆粒(li)，在電(dian)(dian)弧爐中熔(rong)(rong)融(rong)制(zhi)(zhi)得。該(gai)產(chan)品具有純度高(gao)，結(jie)(jie)(jie)晶粒(li)大，結(jie)(jie)(jie)構(gou)致(zhi)密(mi)，抗(kang)(kang)渣(zha)性(xing)(xing)(xing)強(qiang)，熱(re)震(zhen)穩定(ding)(ding)性(xing)(xing)(xing)好，是(shi)一種優(you)良的高(gao)溫電(dian)(dian)氣(qi)絕緣材(cai)料(liao)(liao)，也是(shi)制(zhi)(zhi)作鎂(mei)(mei)(mei)磚(zhuan)，鎂(mei)(mei)(mei)碳磚(zhuan)及不定(ding)(ding)型耐(nai)火材(cai)料(liao)(liao)的重(zhong)要原料(liao)(liao)。廣(guang)泛應(ying)用于冶金、化(hua)工(gong)(gong)、國防、科研、航(hang)天航(hang)空、家用電(dian)(dian)器元件(jian)等。 大結(jie)(jie)(jie)晶電(dian)(dian)熔(rong)(rong)鎂(mei)(mei)(mei)砂(sha)產(chan)品特性(xing)(xing)(xing)：純度高(gao)、結(jie)(jie)(jie)晶粒(li)大熔(rong)(rong)、點(dian)高(gao)結(jie)(jie)(jie)、構(gou)致(zhi)密(mi)；熱(re)震(zhen)穩定(ding)(ding)性(xing)(xing)(xing)好；具有良好的高(gao)溫抗(kang)(kang)折(zhe)強(qiang)度；具有良好的抗(kang)(kang)渣(zha)性(xing)(xing)(xing)能和(he)抗(kang)(kang)腐(fu)蝕性(xing)(xing)(xing)能；導熱(re)性(xing)(xing)(xing)能強(qiang)、高(gao)度絕緣。
